Electric hedge trimmer won't turn on

Symptoms

• No response when pulling the trigger
• Motor hums but blades don't move
• Works intermittently depending on cord position
• Trimmer worked fine until cord was pinched or cut

Likely causes

• CommonTripped outlet breaker or GFCIMany outdoor outlets are GFCI-protected and trip easily, especially in damp conditions.
• CommonDamaged extension cordCuts or pinches in the cord, especially near the plug, are a frequent cause of outdoor tool failures.
• CommonDual-switch safety mechanism not fully engagedMost hedge trimmers require both handle switches pressed simultaneously to run.
• PossibleWorn motor brushesCarbon brushes wear down over years of use and eventually lose contact.
• Less commonInternal wiring fault or blown fuseA break in internal wiring or a blown internal fuse can cut power entirely.

What to do

1. Check the outlet with another device, and reset any tripped GFCI or breaker.
2. Inspect the full length of the extension cord for cuts, pinches, or exposed wire, and replace if damaged.
3. Confirm both safety switches on the handles are being pressed fully and simultaneously.
4. Try a different known-good extension cord to rule out the cord itself.
5. If it hums but blades don't move, stop use immediately, since this can indicate a jammed blade or motor fault.
6. Check for a reset button or internal fuse on the trimmer body if the manual mentions one.
7. If none of these steps restore power, the motor brushes or internal wiring likely need professional service.

Tools and parts

• Multimeter (optional)
• Known-good extension cord

When to call a pro

If the outlet, cord, and switches all check out and the trimmer still won't run, take it to a small appliance repair shop for motor inspection.
